7'0 all 'wife/m t may concern.'

B it known l. Flinn J. SHANisnv, Sr.. a citizen of the United States, residing` at Rochester, in the county of Monroe and State ot New York, have invented certain Improvements in Collapsible Lasts, oi which the followingl description, in connection with the accompanying drawings, is a specification, like reference characters on the dranv4 ings indicating` like parts in the several figures,

This invention relates to collapsible lasts and is herein shown and described in connection with a pretrred form of hinge last. Hinged lasts have come to be regarded as desirable in many types of shoe making because ot' their rapid and positive shorteningl c'li'ect which permits easy removal ot the last from the shoe or insertion therein. Collapsible lasts are generally held in operative lenntlrned position by so-called locking mechanisms of the positive or impositive types. The former, which does not collapse under pressure, is regarded as the better tor many kinds of work, and it is with it that the present invention has to deal. Difficulty has been experienced with the posil tive lock in that when disengaged to permit the collapse oi. the last, it was necessary for the operator to hold the locking` member out of operative position until a portion at least ot the collapsing' movement had been eff cted. a condition which militated against convenience in operation as some special tool was necessary to hold the locking member out of operative position while the collapse was begun, or else the operators lingers were liable to be injured by being squeezed between the last parts while holding the looking member out ot operative position. fi second objl ction to the use ot such lockingmembers has been that when the last was extended again after collapse, some special manipulation was necessary in order to restore the member to operative position.

Accordingly it is an object of the present invention to provide a novel positive lockinodevice tor a hinged last which shall. avoid these and oth r objections. An important teature ot the invention consists in a novel locking: device organized so that. auton'iaticallv. when the lockinef member is displaced trom operative position, it will be Serial No. 480,049.

positively held in inoperative positiom .ieing` preferably released therefrom by the collapsing' movement ot th i last. ln the last shown, this is accomplished by providing a, xed point in a last part, economically chosen as a part of the bonding mechanism, over which the locking memberl hooks or latches automatically as itis displaced from operative position and from which it is unhooked as the last is collapsed, thereby being` able to return to operative `position automatically when the last is ext-ended again.

These and other features ot the invention. will be better understood from thi following description ot a preferred embodiment thereof selected for illustrative purposes and shown in the drawing in which Fig. l is a broken away view ot the hinge and locking' mechanism ot the: last in extended position.

Fig. 2 shows the condition of the parts atter the moving oi the lockingl member from operative position.

Fig. 3 shows thparts after collapse ot the last.

The illustrated last comprises a torepart 10 and a heel part 1Q. having a thimble hole i4- and separated by a cut of any desired torni permitting` hinge movement oi one part on the other, In the last shown the ont comprises a circular knuckle 16 on one last part extending' into a correspondingly shaped depression in the other, the knuckle being; joined to the lower surtacl of the last bv a straight cut 18 well known, and the last parts being' separated at the upper part ot the last by a ll-shaped opening 20 permitting the collapse ot' the last bv relative movement ot the parts around the center of the knuckle.

The two last parts may be bonded in any convenient manner. a very simple bondinn device being shown in the drawing'. This consists oonvenientlyot two identical plates 24- and 2G anchored in that one ot the last parts not containinga the knuckle bv nine 28, C30. Between these plates, g'iiivotally mounted on the pin QS is a lockino; member 32. he pintle 22 passes through the plates and through the center ot the kr" lf3 in the other last part. than. in wombinat on with th plates and the pins Q8, 30. bondingl the two last parts together for hinge movement about the piintl-e 2Q'. Another plate orplates corresponding' to 24 and 26 may be anchored in. the heel. part and bored to accommodate the pintle 9,2, thus strengthening vthe joint if desired. The plates take the tensile stress required to hold the last parts together, and their pivotal mounting at 22 permits the collapseof th-e last.

The locking member which, as has been stated, is pivoted on the pin 2S in one last part has a shoulder 32 which normally contacts with a pin 34; mounted in the other last Y part. rThe shoulder 32 preferably makes an angle with the rline joining the pins 28 and 34 so that it can wedge intov contact with the pin 34 and take up any wear between the last parts. The locking member is shown as slotted at 3G and comprises in the slot aplunger 38 arranged for sliding` movement. A. spring l0 presses the plunger outwardly. The locking member, plunger and spring are mounted between the plates 24 and 26 so that the parts are convenient-ly held against displacement. Means, preferably an abutment in the last, is provided for holding the loc-king; member in inoperative position. Conveniently a portion of the bonding mechanism is utilized for this purpose, as will be seen, thus economizing parts and operations in the last construction. The lower part of the plunger is formed with the cam surface 42 which vis of wedge shape and forms two notches and 45 with the sides of the slot 36, which are preferably lengthened for that purpose. and also to effect e'liicient guidiiur action on L.. the plunger. The plunger normally engages in the notch 48 a part of the bonding mechanism, (the abutment above mentioned) shown as the pin 30 on one side of the angle of its wedge and tends, under the pressure of the spring 40, to wedge the lockingmember up against the pin Sil as shown in Fig. l. When the locking member is depressed by pressing on its handle 411i, which projects into the opening 20' for convenient direct normal operation, see Fig. 2, it rotates about the pin 2S, thereby carrying Athe plunger 3S over to the other side of the pin 30 so that the other notch l5 at the other side of the cam l2 rests on the pin 30. This position is shown in Fig. 2 and it will be plain that pressure of the springl in this position of the parts causes a reaction between the plunger andthe pin 8O which tends to retain resiliently the locking member in inoperative position as shown in said Fi 2. The movement of the locking` member to inoperative position may be arrested at any convenient point in various ways as by contact ofthe handle lll with the pin Bei or by contact of the lower portion of the locking` member with the pin 30 both of which arrangements are shown in Fig. 2. The cam 42 could alone hold thelocking member in its two positions, but the notch construction makes the action more positive and reliable.

lt will be noticed in Fig. 2 that that portion of the cam surface 4t2 which is in contact with the pin 30 makes a slight angle with the line joining,` the pins 2S and 3G which assists the friction of the parts in effecting theholding of the locking member in inoperative position. The locking member, through its plunger 38, is in effect hooked or latched over the pin 30 when in inoperative position and will thereby be held in such position indefinitely without the interposition of tools or the operators lingers to effect this result.

The last is collapsedby a movement of rotation of the heel part relatively to the forepart about the pin 22, as shown in Fig. 3. This movement, through pressure between the pin Se and the locking member, these parts being relatively arranged for this purpose, rotates the locking` member counterclockwise around the pin 2S so that the projection of the. cam 42 ridesback over the pin 30, and the other side of the cam comes into contact with the pin. This is shown in Fin'. 3. The spring' et() now tends to throw he locking member up into operative position and when the heely part vis brought back into extended position, the locking member will rise as soon. as the pin passes the corner of the shoulder 82', and the shoulder and pin will be brought firmly into Contact again, as shown in Fig. l. The locking member, therefore, when thrown out of operative position is automatically held in inoperative position and is restored to operativeness by the collapsing movement of the last.
